JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 296,823, dated April15, 1884.

Application filed January 10, 1884. (No model.)

To all whom it may concern.-

Be it known that we, EDWARD COPLEY, JUsTUs F. SELDOMRIDGE, and GEORGE DELA VERGNE, citizens of the United States, residing at Colorado Springs,in the county of El Paso and State of Colorado, haveinvented a new anduseful Journal-Bearing, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to the manufacture of journal-boxes and journal-bearings made of papier-mach or leatherette, or otherlikematerial, for use on railway-cars and machinery in general.

The main objects of this invention are to produce a bearing-surface thatshall be slow to excite frictional heat and will. not cut or grind thejournal, since it is a well-known fact that simple friction generatescomparatively little heat, while metal running upon metal, in theabsence of oil, is the primary cause of the rapid frictional heatandgrinding in journal-boxes. Ourimproved journalbearing, made ofpapier-mach or leatherette,

obviates cutting or grinding of the journal,

and consequently little or no heating of the box, thus enabling thelubricating-oilto remain in a pure condition much longer than in themetal bearing-boxes.

Vith these and other objects in View our invention consists in ajournal-bearing made of papier-mach, leatherette, or like material.

Our invention further consists in the novel construction of thejournal-bearing, as will hereinafter be more fully set forth,and pointedout in the claim.

In the annexed drawings, Figure l represents one-half of a j ournal-boxbearing made of papier-mach or leatherette; and Fig. 2 represents an endView of a j ournal-box bearing with the improved filling, constituting alining for the bearing-surface. v

To carry out our invention suitable molds, press, or dies areconstructed to fashion and shape the sectional j ournal-bearings. Tomake the journal-bearings entirely of papier-mach or leatherette, thematerial is prepared into a pulpy or plastic condition and run into themold or press in a manner well known in the art of casting or shapingarticles. After the plastic material has settled and become solidifiedinto the article, it is removed and may be subjected to further pressureto make the same more compact and solid, and at the same time give asmooth bearing-surface for a given-sized journal. "When thejournalbearings are made in molds, it will be desirable to subject themto pressure in a hydraulic press, to make the same more compact andsolid, and to secure a desirable and smooth hearing-surface forthejournal. To reline or reface a worn journal-bearing, thejournalbearing is placed in a suitably-constructed mold or press, andthe. plastic material run into the mold for a mechanical connection verymuch like that employed in the Babbitt process of reliningjournal-bearings. After the material has become hardened and united tothe journal-bearing bloclr,the thusfilled box is removed and may besubjected to pressure for a smooth bearing-surface.

In the accompanying drawings, A represents the section made entirely ofpapiermach, leatherette, or equivalent material. Brepresents anothersection of a journal-box, filled or lined with papier-mach, leatherette,or equivalent material. The section B is formed with a longitudinalpassage, .0, with inclined shoulders (I, and also end chambers orrecesses, c, and inclined shoulders f, corresponding with the shouldersdof the longitudinal passage 0. This formed passage and end recessesform a chamber to receive and secure the herein-described filling inposition from displacement.

In order to define more clearly the nature and advantages of ourinvention, we would have it understood that we claim nothing shown inthe patent to Devlan, No. 1,268, dated July 9, 1861.

That we claim as our invention, and to secure by Letters Patent, is-

A journal-bearing section formed with the passage 0, shoulders d, endrecesses, e, and end desire shoulders, f, in combination with a fillingof 5.
